基于网络密度参量的城市街道空间几何性特征定量分析方法

Quantitative Analyses Of Street Network Geometric Structure By Using Network Density Parameters

论文利用街道网络密度作为基本分析参量,构建起"网络密度图表",针对城市空间几何形态特征进行量化描述和分析。通过对天津城市核心区的实证研究,解析了城市的网络空间特征。量化描述方法的建立使得不同城市,以及城市内部各个区域网络之间的比较研究具有了统一的科学评价标准,它为城市研究者及设计师提供了深入理解街道网络内在关联的有效技术手段。

This study focuses on the geometric structure of urban street networks and developed a set of new quantitative devices based on network density analysis to identify the geometrical characteristics of street networks. The method is applied in the empirical research in Tianjin downtown area. The quantitative research of this paper finally provides an effective device for urban researchers and designers to gain an insight into the spatial patterns of urban street networks.
